I think it is fine, although does lead to some minor annoyances.
In 5e you move through ally spaces on a grid because your allies take up more space than their actual bodies do. Here you loose a bit of movement going around your allies.
Corpses/downed allies - yeap, those should be possible to move through. Hell, even prone ones should be fine imho.
